I am not very used to SPARQL, but I managed to write my own query for books and their genres, authors and their dates of birth and death at https://query.wikidata.org
SELECT
?title ?titleLabel
(GROUP_CONCAT(DISTINCT(?authorLabel); separator="//") as ?authors)
(GROUP_CONCAT(DISTINCT(?dateborn); separator="//") as ?date_born)
(GROUP_CONCAT(DISTINCT(?datedeath); separator="//") as ?date_death)
(GROUP_CONCAT(DISTINCT(?datepub); separator="//") as ?date_pub)
(GROUP_CONCAT(DISTINCT(?genre_titleLabel); separator="//") as ?genre_title)
WHERE
{
?title wdt:P31 wd:Q571 .
?title wdt:P50 ?author .
?title wdt:P577 ?date_pub .
?author wdt:P569 ?date_born .
?author wdt:P570 ?date_death .
?title wdt:P136 ?genre_title .
BIND(CONCAT(STR(DAY(?date_pub)),"-",STR(MONTH(?date_pub)),"-",STR(YEAR(?date_pub))) AS ?datepub )
BIND(CONCAT(STR(DAY(?date_born)),"-",STR(MONTH(?date_born)),"-",STR(YEAR(?date_born))) AS ?dateborn )
BIND(CONCAT(STR(DAY(?date_death)),"-",STR(MONTH(?date_death)),"-",STR(YEAR(?date_death))) AS ?datedeath )
FILTER (?date_born > "1900-01-01T00:00:00Z"^^xsd:dateTime) .
FILTER (?date_born < "1905-12-31T23:59:59Z"^^xsd:dateTime)
SERVICE wikibase:label {
bd:serviceParam wikibase:language "en" .
?title rdfs:label ?titleLabel .
?author rdfs:label ?authorLabel .
?date_pub rdfs:label ?date_pubLabel .
?date_born rdfs:label ?date_bornLabel .
?date_death rdfs:label ?date_deathLabel .
?genre_title rdfs:label ?genre_titleLabel .
}
}
GROUP BY ?title ?titleLabel
It works and I get all the genres in the same field. The only way I could get this was with
(GROUP_CONCAT(DISTINCT(
for genres and dates. But If you loook in the results there are records with more than one date. And I want to get only the first date, and not all the stored dates in the database for this record, but I can't.
For example, If I ask for
?dateborn
instead of
(GROUP_CONCAT(DISTINCT(?dateborn); separator="//") as ?date_born)
I get an error. Do you know where is my mistake?

I wrote the following SPARQL query to find the wikidata item with the label "San Leucio" in Italy.
SELECT DISTINCT * WHERE {
?location ?label 'San Leucio'#en .
?location wdt:P17 wd:Q38 .
?location rdfs:label ?locationName .
OPTIONAL {
?article schema:about ?location .
?article schema:isPartOf <https://en.wikivoyage.org/> .
}
?location wdt:P18 ?image .
FILTER(lang(?locationName) = "en")
}
The query returns these 3 results:
wd:Q55179410
wd:Q20009063
wd:Q846499
The result I want is wd:Q846499, which is outside of Naples, Italy. Is there any way I could further filter this query to return the result that is nearest to Naples? I know that I can get the geoCoordinates for each of these with ?location wdt:P625 ?coordinates, but I'm not sure how I could use that to compare to the geo-coordinates of Naples to get what I want.
SELECT DISTINCT * {
VALUES ?naples {wd:Q2634}
?Napfes wdt:P625 ?naples_coordinates.
?location rdfs:label 'San Leucio'#en .
?location wdt:P17 wd:Q38 .
?location wdt:P18 ?image .
?location wdt:P625 ?location_coordinates.
OPTIONAL {
?article schema:about ?location .
?article schema:isPartOf <https://en.wikivoyage.org/> .
}
BIND (geof:distance(?location_coordinates, ?naples_coordinates) AS ?distance)
} ORDER BY ?distance LIMIT 1
I would like to have a list of all mountains names of the "dbo:firstAscentPerson" property of Lionel Terray (dbpedia: http://dbpedia.org/page/Lionel_Terray).
This below is what I have so far
select ?person ?firstAscentPerson where {
?person foaf:name "Lionel Terray"#en.
dbo:firstAscentPerson rdfs:label ?firstAscentPerson.
} LIMIT 100
The following query does what you need:
SELECT ?mountain ?mountainName ?person2 ?person2Name {
VALUES ?person1Name {"Lionel Terray"#en}
?mountain dbo:firstAscentPerson ?person1, ?person2 .
?mountain rdfs:label ?mountainName .
?person1 foaf:name ?person1Name .
FILTER (lang(?mountainName) = "en")
OPTIONAL {?person2 foaf:name ?person2Name . FILTER (lang(?person2Name) = 'en')}
}
I'm trying to grab some definition in dbpedia inside my thesaurus.
Although can find country that have a label that match my country, i don't get all of them. So i try to match similar label with contains but it does not work.
Any idea why.
SELECT distinct ?idbcountry ?label ?labelDb ?def
WHERE {
?idbcountry a skos:Concept .
?idbcountry rdfs:label ?label .
?idbcountry skos:inScheme iadb:IdBCountries .
FILTER(lang(?label) = "en")
Service <http://dbpedia.org/sparql> {
?s a <http://dbpedia.org/ontology/Country> .
?s rdfs:label ?labelDb .
FILTER(CONTAINS (?labelDb, ?label)).
?s rdfs:comment ?def .
FILTER(lang(?def) = "en") .
FILTER(lang(?labelDb) = "en") .
}}
The exact matching query that works is as follows:
SELECT distinct ?idbcountry ?label ?def
WHERE {
?idbcountry a skos:Concept .
?idbcountry rdfs:label ?label .
?idbcountry skos:inScheme iadb:IdBCountries .
FILTER(lang(?label) = "en")
Service <http://dbpedia.org/sparql> {
?s a <http://dbpedia.org/ontology/Country> .
?s rdfs:label ?label .
?s rdfs:comment ?def
FILTER(lang(?def) = "en")
}
}

Without seeing your data, we can't know why your query isn't working. However, using contains is pretty straightforward. It's just a matter of contains(string,substring). As Jeen said, we can't reproduce your problem without knowing what your data looks like, but here's an example of contains in action:
select distinct ?country ?label {
?country a dbpedia-owl:Country ; #-- select countries
rdfs:label ?label . #-- and get labels
filter langMatches(lang(?label),"en") #-- but only English labels
filter contains(?label,"land") #-- containing "land"
}
SPARQL results
To get movie detail from linkedmdb, I used sparql query :
PREFIX mdb: <http://data.linkedmdb.org/resource/movie/film>
SELECT DISTINCT ?Title ?Genre ?Actor ?Country ?Director ?Year WHERE {
?film mdb:id ?uri .
?film dc:title ?Title .
?film movie:genre ?filmgenre.
?filmgenre movie:film_genre_name ?Genre .
?film movie:actor ?cast .
?cast movie:actor_name ?Actor .
?film movie:country ?Ctr .
?Ctr movie:country_name ?Country .
?film dc:date ?Year .
?film movie:director ?Drc .
?Drc movie:director_name ?Director
FILTER regex(?Title, "Kingdom of Heaven")
}
But SPARQL results shown Title same as counted Actor . How to combine the query so that Title is not repeated?
I've try using GROUP_CONCAT but not working in LinkedMDB Endpoint?
Could someone guide me?
SELECT ?book
WHERE {
?book a dbpedia-owl:Book .
?book WHAT_PREDICATE 'Agatha Christie'
}
I want to know what predicate to use in the query. I haven't found any list with books or writers predicates on DBPedia.
SELECT ?book
WHERE {
?book a dbpedia-owl:Book .
?book dbpprop:author ?author .
?author dbpprop:name ?name
FILTER regex(?name, "Agatha Christie", "i")
}
